xutingjun 67ad12d793 [SPARK-8392] RDDOperationGraph: getting cached nodes is slow ... ```def getAllNodes: Seq[RDDOperationNode] = { _childNodes ++ _childClusters.flatMap(_.childNodes) }``` when the ```_childClusters``` has so many nodes, the process will hang on. I think we can improve the efficiency here.
